The given percent above is 215%. To convert this into decimal, let us divide this by 100. 215 / 100 and we get 2.15. So the decimal form of 215% is 2.15. Next, convert it into a fraction. Given the decimal form of 2.15, this is already equivalent to 2 15/100. To simplify this, since both 15 and 100 are divisible by 5, we get 3/20. Therefore, the fraction is 2 3/20. So the correct answer is option B. 2.15; 2 3/20.
Answer:
Step-by-step explanation:
Since (8x-20) and (3x+2) are two sides of the angles on one plane, we can structure them into an equation to find x.
(8x-20) + (3x+2) = 180
We want x to be on one side and all the numbers to be on the other. But first, we must combine our two problems.
-20 + 2 = -18; 8x + 3x = 11x
So now our equation is:
(11x-18) = 180
In order to move our numbers to one side and leave our x's on the other, we must inverse our additions/subtractions/etc.
180 + 18 = 199
11x = 199
199/11 = 18.1
x=18.1!
